hi,
I just bought a 93 automatic sc that has bad head gaskets with the factory exhaust. I was curious what the factory boost usually is. I just wanted to know if my car has been modded any.
thanks alot
 
hmm..

Each car is going to be a little different, you should probably push 11-12 PSI max for a stock car. I always hit about 11 in my car and it climbed another 1 PSI as the rpms went up. Though my friend with his stock 91 SC pushes 9 PSI and then climbs to 11. Anything over 12 with a 93 Auto and it could be a possibility that you car is modified.
 
My stock 91 with removed air silencer makes 10 right away, 11 by 3000, and 12.5 by 4500. Of course that varies some depending on atmospheric conditions. It has over 100K on it.
